名称:
                                Novel formation of dienes with greater steric congestion resulting from the Diels–Alder reaction–desulfonylation sequence of 4-acyl-4H,6H-thieno[3,4-c]furan 5,5-dioxides
                             
                            
                                摘要:
                                已合成4-酰基-4H,6H-噻吩[3,4-c]呋喃5,5-二氧化物,并提交给Diels-Alder反应,以获得在去磺酰化后具有较大立体拥堵的二烯。
